Websocket: Logs Subscribe

[kasahh]

Are some transaction signatures excluded from log subscribe? I noticed "logs_subscribe" does not output all transactions occurring on the solana blockchain. For example, I started the log_subscribe websocket and passed the incoming stream to a text file, then I created a pool on raydium and afterwards retrieved the transaction signature for that pool creation event. When I searched for the signature in the text file, it got no match even though there are thousands of transactions recorded during that time. But on solscan, the signature search returned the pool creation details as expected

So my question is, are some transactions excluded from logs subscribe and if yes, how can i get all transaction events via websocket?
